IMPROVEMENT IN LATCHES FOR (:IATES.v

Specification forming part of Letters Patent No. 122,061, dated December19, 1871.

To all whom it may concern:

Be it known that I, HENRY W. ROBIE, of Binghamton, in the county ofBroome and State of New York, have invented certain lm novements inLatches for Gates or other purposes, of which the following is aspecification:

The invention relates to that class of latches in which the bolt iswithdrawn from the catch by means of a latch-rod or spindle arranged atright angles to the bolt, and provided with an inclined orcam-face whichengages with a correspondingt'ace in or upon the bolt in such mannerthat as the latch-rod is thrust inward its inclined face shall thrustthe bolt backward, the bolt being returned to its place by a spring asthe latchrod is Withdrawn. The invention consists of certain details ofconstruction which will be explainerh the object of the invention beingthe construction of a reliable and efficient latch that may be readilyapplied and conveniei-itly oper ated, and that shall recommend itself tothe public.

Figure 1 in the accompanying drawing is a section of a side elevation ofa gate with the device attached embodying my invention, showing theparts in position. Fig. 2 is the latch-rod detached. Fig. 3 is thecatch. Fig. i is the divid ed flange or rose. Fig. 5 is the latch orbolt; Fig. 6, the cylindrical case.

A is the latch or bolt which works in the cylindrical case B. This latchhas alongitudinal.

slot, (4, corresponding to slots 1) b in said case, which has a flangewith holes for screws to hold it in place. 0 is the latch-rod whichworks at a rightangle with the latch A and has a flattened end, 0, whichis tapered from the inside to an angle-ot' about forty-five degrees,extending near] to the end, leaving a nib or projection, e, whichextends through the slot 1) in the cylindrical case B into the slot a inthe latch, and prevents said latch from being thrown out of place by thespiral spring I), which is .placed in the end of the. case B. Thelatch-rod U is operated by the knob E and prevented from being thrownout of posi (ion by the reaction of the spring by the guidesocket F,whichis secured in place by screws. This socket is made in two parts,for the purpose of applying it between the shoulders g g. G is thecatch, which has inclined sides and an oblong hole for the latch toenter to allow for the settling or depression of the gate.

The gate is opened by pressing upon the knob E, thereby engaging thetapered or inclined end of the latch-rod (J with the end of the slot ain the latch or bolt A, which disengages it from the catch G andcompresses the spring D, which i by its reaction throws back the boltand latchrod to their places. The gate may then be relatched by pressingthe latch against the inclined side of the catch in the ordinary manner,or the knob may be held down until the gate is closed. 1

This device may also be attached to windows for looking or holding themin position.

From the above description it will be seen my construction andarrangement are very simple and can be cheaply made. As the latch-roddoes not extend through the shell B I am obliged to provide a shoulderor stop, 9, to prevent it from being thrown out of its place as the boltsnaps forward.

It being cheaper to cast the said rod with its shoulder g and the knobin one piece, I have done so, and then make the rose F in two parts, sothat it shall when applied fit the rod closely, and serve as a stopagainst the under side of which the shoulder shall strike.

I claim as my invention- The combination of shell B, recessed bolt A,spring D, vertical latch-rod 0 provided with the beveled end 0, shoulderg, and knob E with the divided rose F, substantially as set forth.
